For sale: **Set of two 60-watt light bulbs** purchased for heating a cockatiel. My cockatiel's health declined, and the veterinarian instructed me to switch to 40-watt bulbs instead of 60-watt bulbs if using a plastic sheet, as the 60-watt bulbs were deemed dangerous. Therefore, I am selling these. ◆ Condition ・Set of 2 x 60W light bulbs ・1: Unused (new) ・1: Nearly unused (Used for approximately 2 weeks / about 10 hours a day) To distinguish the used bulb, the nearly unused bulb will be shipped in a 40-watt bulb box. ※The box is labeled "40W," but the contents are 60-watt bulbs. ※Please check the photos. ◆ Notes ・Cover and fixtures are not included (bulbs only). ・Please purchase only if you understand the condition. ※I am also selling on other sites, so please comment before purchasing. If you have any questions, feel free to comment. Thank you.
